scientific calculator

A scientific calculator is an electronic calculator designed to perform both basic arithmetic operations (addition, subtraction, multiplication, division) and advanced mathematical functions such as trigonometric, logarithmic, exponential, and statistical calculations. It is widely used in educational and professional fields for quick and accurate handling of complex mathematical tasks. Scientific calculators often include features like scientific notation, floating-point arithmetic, constants (like π and e), complex number calculations, matrix operations, calculus functions, and conversions between different units. Some models also have programmability and computer algebra capabilities. These calculators are essential tools in mathematics, physics, engineering, and other sciences, and they are frequently required for exams where computers and smartphones are not allowed.
